Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.
Drop it.

Define a typed sort function using DEFINE_LIST_SORT_DEBUG for the
mergesort sanity check instead of using llist_mergesort(). This gets
rid of the next pointer accessor functions and improves the performance
at the cost of slightly bigger object text.
Before:

With this patch:

Mark a test that was recently added in e031e9719d2 (test-mergesort:
add test subcommand, 2021-10-01) as passing with SANITIZE=leak. It
will now be listed as running under the
"GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI
target).

Adapt the qsort certification program from "Engineering a Sort Function"
by Bentley and McIlroy for testing our linked list sort function. It
generates several lists with various distribution patterns and counts
the number of operations llist_mergesort() needs to order them. It
compares the result to the output of a trusted sort function (qsort(1))
and also checks if the sort is stable.
Also add a test script that makes use of the new subcommand.
